In this study, nano-ZrO 2, which was treated by silane couple agent, incorporated in phenyl silicone rubber at low concentration (≤3.0%) and cured by Room Temperature Vulcanized (RTV) method. The effects of different additive amount of nano-ZrO 2 on the mechanical properties, thermal conductivity and electrical conductivity of phenyl silicone rubber were investigated. The thermal conductivity, tensile strength and volume resistivity of nanocomposites increased firstly and then decreased. The

We were interested to find that phenyl silicone rubber had a maximum thermal conductivity (0.399W/(m· K)), a maximum volume resistivity (1.08×10 12 Ω·cm)and a minimum dielectric constant (2.775), with a definite total mass fraction of the particle (0.06%). Compared with the thermal comductivity of pure silicone rubber (0.130W/(m· K)), it increased more than three times in the addition amount of 0.06wt%. Moreover, the silicone rubber keeps a high tensile strength.
